Imaging flats

Below are tables that provide estimates for the maximum number of counts for a given exposure time using the imaging lamp. Please check the count level before acquiring several flats in a row because the lamp intensity may vary with time and dichroic type. . ... Note: Table is being built. Sorry for the inconvenience.
